An information processing device, method thereof and a recording medium for easily switching input signals. A broadcast connection and a point-to-point connection are established between the receive device and the transmit device. When the user commands the canceling of the P.P. connection established for the receive device or the transmit device, only the broadcast connection remains established. In this state, the user receives signals on a receive device sent from the desired transmit device, and commands the restoring of the P.P. connection with the desired transmit device. The switching of input signals to the receive device is in this way performed by temporarily canceling the P.P. connection.
